Jennifer Lopez, You Were So Hilarious As The Host Of 'Lopez Tonight!'

Hey, Jennifer Lopez — if you get tired of acting, singing, and dancing, you could have a future in stand-up! The uber famous star did the opening monologue for Lopez Tonight, in place of George Lopez on Monday Dec. 18 … and she killed it!

J. Lo opened the show with a hilarious stand-up bit! “Welcome to Lopez Tonight, where nobody gets fired … they just get replaced by a bigger star with the same last name.” She took another shot at NBC, saying “A bar is making a drink for Conan [O’Brien] … it’s called ‘The Go Back To Manhattan’ — it’s a Manhattan with sour grapes and a knife in it.”
